Bartlett and Barrington Hills were the only holdouts in Cook County's Northwest suburbs on a referendum allowing municipal leaders to negotiate with companies other than ComEd for their electricity supply.
Bartlett voters were decisively against the proposal, with 61 percent voting down the measure. The question was closer in Barrington Hills, where 468 voters opposed the proposal and 443 backed it.
Voters approved the referendum in Arlington Heights, Barrington, Buffalo Grove, Deer Park, Hanover Park, Hoffman Estates, Mount Prospect, Palatine, Park Ridge, Rolling Meadows, South Barrington and Wheeling.
While not every Northwest suburb chose to put the electricity aggregation referendum on Tuesday's primary ballots, those that did not -- including Schaumburg and Lake Barrington -- were very much in the minority.
Municipal leaders in communities that backed the referendum can now negotiate with power companies other than ComEd to obtain lower rates for residents and small business. ComEd will continue to provide infrastructure and deal with outages.
